hi, this is a case where wiremold looks wonderful!
i really feel sorry for you...i have been there and it is a terrible place to be, but not near as bad as trying to get paid for the additional labor and sometimes material to pull off the job...
i would just stay away from the unknown...its too hard to bid..now time and material is a different story..
good luck let us know what you do so that it may save me or someone else next time
